Application filed January 5, 1328. Serial No. 510,883.

To" all whom it may concern: Be it known that we, Crieis'rornnn STRAGHAN. and DAVID J. InIsH, citizens of the United States, residingat South Orange and St. George, Staten Isl-and, in the counties of Essex and Richmond, and States of New Jersey .and New York, respectively, have invented certain new and useful Improvements in an Oil Pipe and Burner. Coupling, of which the following is a specification, reference being had, therein to the ac 'conrpanying drawing. 1 I 7 Our invention relates to" improvements in couplings for connecting oil supply pipes with burners, such as those used in connection with numerous oil burning systems for boiler and other furnaces, the principalob- 'ects bein to rovide a sim ale and efficient b assocition-ofparts which will-prevent the burner from beingwithdrawn from the furnacewhile it is lighted, and to providea uniqueconstruction which will permit the burner to beadjusted inwardly or outwardly as occasion may demand.

, Wi l the-foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings. 1 l b F gure 1 is a perspectiveview of our in ventio'n showing its, application in connection' with a burner and anair register through which said burnerpasses.

Figure 2 is a side elevation partly in'ver tical section.v 1

Figure 3 is 'aplanview-of the two-section bracket whi'ch rigidly carries the coupling member of the oil pipe and permits adjustment of the burner when: the latter is operatively associated with said coupling member.

, Figures 4 and 5- are ,vertica'l' sectional views as indicated by lines 4-4 and 5 -5 of In the drawings above briefly described,

the numeral 1 designates an air register adapted to be secured to the front of a furnace and having a central hub '2 through d which a tubular oil burner 3; passes. This burner is provided witha laterally extend ing neck 4 constituting a couplingmember, the lower side of sand neck being provlded inathe present disclosure, with an annular concave .surface'5 to contactwith an annular convex-surface '6 of a stationary .couplmg member 7, the latter being suitably connected with the end of a flexible oil supply pipe '8, the two coupling members i and 7 being clamped tightly together by means yet to be described; The common axis. of the annular surfaces 5 and 6, it is to be-observed,

is transverse to and offset laterally. from the longitudinal axis of the burner 3.

In the present showing, the coupling memher 7 passes through an opening 9 in a transverse horizontal plate 10 forming an adjustable outer section' of a bracket, the inner section of said bra-cketbeing preferably formed by another plate 11 which may be rigidly secured to the hub 2 or to any other suitable part by cap screws or the like 12. We prefer to provide the upper portion of the coupling member 7 with a shoulder 13 resting on the plate 10 and to thread a nut 143011 the lower end of said member 7 to contact with the lower side of saidpla-te, thereby rigidly holdingsaid coupling member and screw will permit the yoke 16 to be swung outwardly so that the burner 3 may be rotated and disengaged from the coupling member 7, whereupon said burner may be withdrawn, Provision is made whereby the burner cannot be withdrawn from the furnace until it isdisengaged from the coupling member 7 and thus it is insured that said burner cannotbe removed while the atomized fuel therefrom is ignited. Any desired adjustment" of the burner inwardly or outwardly however,may be'made, for which purpose the plate 11.

We prefer that the plate lIO'sliall rest slidably upon the upper side ofthe plate lland that it shall be provided with a rib or shoe 18 adjustably received in a" longitudinal slot 19 in plate 11, said shoe bein provided with a depending stud 20 upon wiich'a nut 21 is threaded to contactwit-h the lower side of plate 10 i's adjustable along the the plate 11 to normally hold the plate 10 against movement. By loosening this nut, the entire burner and the coupling means for the ipe 8 may be adjusted inwardly or out-- war dly as occasion may require. Then, by tightening the nut 21, the parts will be held rigidly in adjusted position.

Attention is directed to the fact that the bracket section or plate 11 is permanently secured to the air register 1 or to any other desired support through which the burner 3 passes and while the connection between the two bracket sections 10 and 11 permits adjustment of the former along the latter, said section 10 cannot be moved forwardly away from the section 11 and consequently, the burner 23 cannot be removed while it is in operation. In order to re move this burner, it is necessary first to release the screw 17 and swing the yoke 16 outwardly, thus permitting the coupling member 4 to be disengaged from the coupling member 7.- Obviously, the oil supply through the pipe 8 should be cut off before disconnecting the coupling members 4 and 7, but if through iuadvertence the supply is not shut off and thus the burner continues to operate, the passage of oil to said burner and continued operation of the latter while it is being removed, is prevented by disconnection of one of the coupling members from the other. It is thus insured that the burner cannot be removed from the furnace into the furnace room while it is blaz ing and thus the fire hazard is reduced to a minimum.

Attention is further directed to the fact that the connection between the coupling members 1 and 7 is broken by rotation of the burner instead of outward sliding of the latter, as in similar burner connectionsheretofore devised. In the connections to which we refer. an elongated male coupling member carriedby the burner must be withdrawn from a stationary female coupling member, by sliding the burner outwardly. with danger of totally withdrawing the latter from the furnace while still blazing. By the construction which we employ, the burner is not moved outwardly to any extent whatever to separate the two coupling members and consequently such an occurrence cannot take place.

Further attention is directed to the relation of the contacting surfaces 5 and 6. with respect to the longitudinal axis of the burner 3. Not only does this arrangement permitseparation of the two coupling members 4: and 7 by rotation of said burner, but the arrangement in question greatly facilitates re-application of the movable coupling members-4 to the stationary member 7 when the burner is reinserted into the furnace, after it hasbeen removed for cleaning or the like. It will be observed that when re applying the burner, it is simply necessary to slide the latter through the hub 2 the proper extent and then rotate said burner about its longitudinal axis, so that the two coupling members may properly engage each other. During this operation, it may be necessary to effect some slight additional longitudinal sliding of the burner as the two members come together, but no lateral shifting of the burner is necessary to properly engage its coupling member with the stationary member 7.

As excellent results may be obtained from the details disclosed, they may well be followed. It is to be understood however that within the scope of the invention as claimed, numerous changes may be made.

lVe claim:

1. In combination, an elongated burner and means for rotatably and slidably supporting the same, said burner having a laterally extending fuel inlet neck provided with a coupling member, a stationary oil conducting coupling member normally engaged by the first named coupling member, the two coupling members having contacting co-axial annular surfaces whose common axis is transverse to and offset laterally from the longitudinal axis of the burner, and means for normally securing said coupling members together. said first named member being separable from the stationary member by merely rotating the burner about its longitudinal axis when said securing means is released.

2. In combination, a burner having a coupling member offset from the longitudinal axis of said burner. an inner bracket section adapted to be rigidly secured to a support through which the burner may be adjusted, an outer bracketseetion adjustable on the inner section on a line parallel with the burner axis, an oil pipe having a coupling member rigidly carried by said outer bracket section, and means for clamping the two coupling members together.

In combination, a burner having a coupling member offset from the longitudinal axis of said burner. an inner bracket section adapted to berigidly secured to a support through which the burner may be adjusted, said bracket section having a slot parallel with the burner axis, an outer bracket section having a shoe and a clamping bolt passing adjustably through said slot. an oil pipe having a coupling member carried by said outer bracket section, and a clamp releasably securingthe two coupling members together.

4. In combination, a bracket member adapted to be stationarily carried by a support, an oil pipe having a coupling member adjacent said bracket member. a burner adapted for slidable passage through the support, said burner having a rigid coupling member held in detachable engagement with the first named coupling member, said coupling members being'movable with respect to said bracket member when sliding said burner from one position to another, and means for holding sald first named coupling I member in adjusted position on the bracket member to secure the burner in adjusted position with respect to the support.

In testimony whereof We hereunto affix 10 our signatures.
